[Tip] Battery charge before Flash

You wake up in the morning, anxious to flash the cool new ROM you discovered last night only to find your raph has 10% battery left... how typical!
You know you need to wait about 2 hours to get at least 50% charge before you can flash away... NOT ANY MORE.
I couldn't find it anywhere in here but I found out you can start flashing over cable even with 10% battery, all you need is to enter bootloader (voldown+softreset) before you start the flashing utility

Or just flash from SD card.
It's also a lot faster, and maybe more safe too.

I wouldn't flash your phone if your battery is under 10% due to the 2 possibly 3 resets it will do during the flash, just to be on the safe side anyways.
Only opinion, do whatever you want with your phone =p

There are good reasons that it requires you to have a charged battery before flashing, as a general rule it's really not a great idea to flash at 10%. You can do it, but at least now you can't say nobody told you

Well considering I prefer flashing over cable (bootloader doesn't like my 8GB SDHC for some reason) the phone is powered and charging from USB during whole flashing process. If the power fails, so does flashing. Where's the problem?
Was really pissing me off to wait 30 minutes to charge from 35% to 50 and I never heard that flashing from bootloader doesn't check the battery level, even when I googled for a way to override it. This might actually help someone like me

Used this today when I had 30% battery. Works fine, and I don't see that if you have about 15% battery or more, that it's much risk seeing as you've got HardSPL and the phone can get power from USB anyway.

The phone doesn't charge while you're flashing, just so you know. More accurately, it doesn't charge in bootloader, so technically if you had some issues which got you stuck in bootloader you could run your battery down. That is the reason it is RECOMMENDED, not required that you have at least half your battery.

When I wake up in the morning my phone is at 100% because I take a couple seconds and plug it in on my night stand before I got to sleep been using WinMo phones too long now.. this is a habit to top it off daily

[Q] Power Issue.. Please Help!

Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem

So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Battery Issue

I have been using Nexus 5 for a year and half now. After upgrading to android 6.0.1 recently, I have been facing serious battery issues, such as:
1. Sudden shut down of the device, from various % of battery remaining. After trying to switch back on, the battery shows empty, or even 5-10% charge remaining.
2. If I charge it fully and then switch to safe mode, the phone works fine, the discharge rate is pretty stable and long-lasting. If I then try to switch back to normal mode from safe mode with a simple restart, the battery percentage again shows drastic change in between the two modes.
3. Sometimes when I keep it in safe mode, the battery percentage shows an increase, even if it's not charging.
* Yesterday I did a factory reset, yet these problems continue. I am confused about this being a battery problem, android bug or something else entirely.
I am a newbie in this forum, so please pardon me if I am missing some things here. Any help would be much appreciated. Thanks

I was about to open a new thread but it looks like we have the same problem, in particular this
1. Sudden shut down of the device, from various % of battery remaining. After trying to switch back on, the battery shows empty, or even 5-10% charge remaining.

Yesterday evening I charged my N5 to 100%, used it 5-10 minutes while in bed and turned it off; this morning I turned it on, used it for other 5 mins (the charge was 86%) and it shut down on its own: when I tried to switch it back on it appeared to be completely discharged.
This happened several times in the last weeks, alongside a way faster discharge of the battery.
Is there a way to check if this is related to some software or it a physical problem of the battery? And, in case, is it possible to change it?

Flash back to stock LP to see if the problem goes away. If the problem continues, it could be time for a new battery.

I've not been playing with roms and stuff for a while and I don't remember that, if I flash stock LP (I'm on stock Marshmallow now, if that matters) will I have everything on my phone wiped?

...anybody?

You could try flashing everything except the userdata.img file. After flashing the other partitions, erase cache before booting the LP ROM for the first time.
I always recommend taking a back up of your data before flashing anything to the phone as there is always the possibility that something goes wrong.

What about calibrating your battery?

I tried to install an app to calibrate the battery but I'd need to root my phone to make it work (as now it's not rooted), and if I remember correctly the root process would wipe my phone (and as right now I don't have much time for that I'd rather try first everything I can without wiping).

Alright, though I'm afraid it might come down to that..
But lemme know anyway if you managed to fix your battery issue without having to calibrate the battery. I had a similar problem but it hasn't gone away yet even after calibrations. Maybe a new battery is in order.

How to fix Nokia 3 Not Fully Charged when you have twrp

I'm making this post because I have seen many people complain about their batteries not reaching 100%. This solution works if your problem started after you flashed/booted TWRP. If you have this problem and you have never booted into TWRP, I'm not sure this will work for you.
I noticed that everytime I booted into TWRP - especially if I made a system backup, my battery would not charge to 100%. Initially I solved this problem by disconnecting my battery then reconnecting this, but this will void your warranty and I realise that most people would not want to go this route.
Perhaps it's a bug in the version TWRP that is available for the Nokia 3, or maybe it's not really compatible with it, but whatever the case, in my experience, the battery is always reading 50% regardless of what percentage the battery was on before, and charging never affects the state.
Anyway if you find yourself in this situation, this is what you should do:
1. Let your battery run down till it reached 0% and shutdown.
2. Boot into recovery (holding the power down and volume up buttons while the the phone is plugged into your laptop till the countdown reaches 0)
3. Once your phone enters recovery, unplug your phone and leave it for a while (15 mins or longer). When I tried it, I initially wanted to wait till my phone ran down but I was too impatient to wait that long. Some people have recommended formatting your cache partition, you can try that too; it cannot hurt.
4. Restart your phone and start charging.
Hopefully it will reach 100%. If it doesn't repeat the same process and wait a longer period of time in recovery, say 30 mins or until the phone powers off.
If you don't have twrp or a custom recovery you can still try the above process although I can't guarantee that it will work for you

Mine seems stuck on 80% after December patch, not rooted, bootloader is locked.

Ok, but have you thought of trying what I suggested? Booting to stock recovery after the battery has run down? Like I said before, I believe the phone is reading the battery status wrongly and when it sees the battery at 0% it shuts down even though the battery level isn't actually 0

Battery calibration will solve the problem.

Question About battery capacity and pmic

Hello, i charged my poco x3 pro to 80%, accubattery indicated that the battery was at 4.2v and at 4800mah, i restart the bootloader and restart again and now I have 100% battery at 4.2v with 5060mah
Is this that just happened the fault of the pmic? or is it a bug in the bootloader?
on older motorola models, I remember updating the firmware also contained a pmic.img, something like:
fastboot flash pmic_a pmic.img
if something like this existed for the device, would it help?
do I need to charge to 100% every time when i change roms to make sure i have good battery voltage?
i say to avoid establishing a 100% wrong in the battery.

Simply charge your device up to 100% and your problem is solved.
A lot of people worry way too much about the battery. I have always charged my devices to 100% and have never noticed a noticeable drop in capacity over the years. My oldest device still in use has been charging from 1-5% to 100% for 6 years.

Chargin to 100% is not the same as fully charging!
Use the App Battery Log by example: https://play.google.com/store/apps/details?id=kr.hwangti.batterylog&hl=de_CH&gl=US
If you charge from 99% to 100% it takes a few Minutes. from 100% to "Full" takes WAY Longer.
Same if you plug a USB Power Monitor and measure how much current flows trough your charger. Even if the phone says 100% there is still more going in.
So connect it to the charger over night and restart the next morning.
There are also people saying "You need to shut the phone down and charge it then" but imho that makes no difference.

If you get root, use command in terminal:
Code:
su
dumpsys battery
Or with PC adb command line:
Code:
adb shell dumpsys battery

Good afternoon! My battery behaves exactly the same, after switching to the bootloader and back to the system, the indicators change a lot, it was 85% after the reboot it became 100%, did you manage to find out the reason ?!

Hi, I had the same issue on my device, seems like I fixed it temporary by rebooting the phone to bootloader until the battery percentage didn't changed, and then I flashed miui 13.0.8 via recovery but now I'm getting a problem with the proximity sensor, it mostly happens when I have the device in the pocket, the same happens with the ambient light sensor in both miui and custom ROMs
